Application filed October 1, 1927. Serial no. 223,430. I

This invention relates to type swaging machines and particularly tomechanism for holding type blanks on. bars and feeding them intocooperative relation with the dies, and then ejecting them after theswaging operation has been performed.

One object of the invention is the provision of means for automaticallyclamping the blanks orbars in position on a head as they are moved intocooperative relation with the dies.

Another object is the provision of means for automatically releasing theclamps as the clamping head is moved away from the dies after theswaging operation hasbeen performed.

Other objects will be apparent from the following. description taken inconnection with the drawings in which Fig. 1 is a top plan view of theclamping head.

Fig. 2 is a side view of the clamping head, with a part of one of thearms of the head broken away.

Fig. 3 is a face view of one of the arms of the clamping head.

Fig. 4 is a section on the line 1-4 of Fig. 3

'Fig. 5 shows the means for alining the;

head as it is moved into swaging position.

The drawings show only so much of the machine as is necessary todisclose this improvement.

The shaft 10, (Figs. 1 and 2),is mounted in a carriage 11 slidable onasupport12.

Means, not disclosed, is providedlfor moving the carriage to the rightto the position shown in Figs. 1 and 2 and then to'the left to its homeposition. Any suitable rack and gearing construction may be provided torotate the shaft one-quarter turn clockwise, (Fig. 2) as the carriage ismoved toward the left to its home position.

The shaft 10 carries a clamping head 15 provided with four arms 16 ofidentical construction. j

Each arm 16 carries a clamp housing 17 suitably secured thereto by screwbolts 18, (Fig. Each housing is provided with two recesses 20 receivingpairs of clamping blocks 21 and 22 pressed apart by springs 23 suitablyanchored to'the block 22 as shown in Fig. 4;. The block 22 is heldstationary v by a screw bolt 24 passing through the housinglZJ The block21 is movedtoward'the block 22 by a wedge 25 which cooperates with anedge of the block and a wedge face v I EJE'SAsi rarest crates.

26 constituting one side of the recess 20; v

The blocks 21 and 22 are provided with cooperatlng wedge faces 27 and 28to force the block 21 laterally as it is forced toward the block 22, theblock 21 being shorter than the recess 20 to permit such movement. Theblocks 21 and 22 define blank holding recesses 29. The construction issuch that blanks.

their respective blocks21 by a double wedge faced plunger 30, (Figs. 2and 3), suitably guided in a slot in the housing and repressure will beapplied to four sides of the i tained therein by alimiting screw bolt 31se 1 cured inthe housing and cooperating with a slot in the plunger. Theplunger isv normally urged into its outer position by a spring 32mounted in a hole in the housing and suitably retained therein by ascrew plug 33. 4 p

One end of the plunger 30 projects through the housing and is providedwith a head 35 (Figs. 1, 2 and 3), cooperating with the end of a plate36, secured to raised seats 37 on the support 12 by bolts 38 andconstantly urged downwardly by springs 39 on bolts 40 screwed into saidseats.

The plate 36, (Figs. 1 and 2), bears on cylindrical fulcrum rods 44seated in correspondingly formed recesses in the plate 36 and seats 37at a point midwaybetween the bolts". 38 and 40. The

bolts 38'and 10 are equipped with adjusting nuts 15 by means of whichthe plate36 may be adjusted about a horizontalaxis and the W propercompression placed on the springs 39. Lock nuts 46 cooperate with thenuts 45130 maintain such adjustment.

The left hand end of the plate 36, (Fig. 2), is provided with a wedgeface 50 against which the head 35 of the plunger. 30 is moved as theclamping head 15 is moved into the swaging position shown in Figs. land2. The wedge face 50 depresses the plunger 30 and, as isapparentfromFig; 3, clamps the blanks securely in position for theswaging operation. The springs 39 hold the plunger depressed until theclamping head is moved toward the left. i

After the swaging has been performed, the clamping blocks 2-1are"perm'itted to be moved into their releasing position by the springs23. As the clamping head is .lllOVGtlhOWVfll'd the left, the plungerhead is moved away from the plate 36 and the plunger 30 is restored byits spring 32. This frees the wedges 25, (Fig. 3) ,which may now bemoved toward each other to release the blocks 21 by plungers 54.suitably supported in the clamp housing 17, each having its inner endengaging the small end of its corresponding'wedge 25 and its outer endpro-I jeeting beyond the housing and provided with a conical head-55 towedgingly engage with wedges56, (Figs. 1 and 2) on the support 12 as theclamping head 15 is rotated during its movement to the left into itshome position. This permits the sWaged type bars to drop out of theclamping blocks.

Each clamping arm 16 is suitably recessed to receive two ejectingplunger-s60, (Figs.

'1, 2 and 3), each of which as shown in Fig.

I f 8,.over-lies the recesses 29 in a pair of blocks I tatedcounter-clockwise.

"2'1 and 22. Cooperating with the pair of plungers in each arm 16 is aplunger 61, (Figs. 1 and 2) slidably mounted in the arm with its endsprojecting beyond the lat- "eral sides of the arm.

As shown in Fig. 1, the carriage 11 is provided with a wedge-piece 62suit-ably secured v thereto as by, screw bolts 63 and which cooperateswith the upper end of the plunger 61. as viewed in Fig. 1 to move theplunger v61 into the position'shown in the center of this figure asthe-clamping head 15 is ro- The plunger 61 is provided with a head 64having one of its sides' shaped to conform to the periphery of the hub,(Fig. 2), on the clamping head to hold the plunger against rotation. The

plunger 61 is recessed at 65 to cooperate with the rounded ends of theejector plungers 60. As shown in the left of Fig. 1, the plungers 60 arein their moved position. .As shown in the right hand part of thisfigure, the plungers 60 are in their retracted position. This positionthey were permitted to'assume 'when'the blanks were inserted with thearm 16' under the wedging piece 62 as shown in After the swaging hasbeen performed, the clamping head is withdrawn and rotated. As it isrotated,-a wedging piece 66, (Figs. 1 and 2), on the support 12 raisesthe plunger 61 which moves the plungers 60 radially outwardly and ejectsthe swaged type bars.

The clamping head 15., (Fig. 2), is pro-- 7 vided'withan indexing andalining disc 67 tion.

suitably secured thereto by screw bolts 68.

. The disc is provided with alining notches 69 which cooperate'with afixed aliner 70 as the clamping-head moves into swaging posi- Thealineris suitably secured to the support 12. I
